WIRE 7 HEAD FOR. LOOMS.

5 Application filed February 21,1922. Serial No. 538,269.

To allwhomz'tmay concern:

Be it'known that we, OLIVER J. PIOKARD and F RED 'PIoKARD, citizens of the United States, residing in Philadelphia, Pennsyl- Vania, have invented a Wire Head for Looms, of which the following is a specification.

This-invention relatestof' wire heads employed in carpet, plush and similar looms, whose function it is to hold the pile wires, the obj ect of the invention being to provide novel and improved means for securing the wire in the head.

The invention will be readily understood by those acquainted with the art from the attached drawings, in which:

Figure 1, is a View in perspective of a common form of wire head;

Fig. 2, is a view in perspective of that portion of one of the wires which is secured in the head;

F ig. 3, is a View in perspective of the se curing plate constituting an element of the present invention;

Fig. 4, is a view in perspective showing the wire assembled in the head in accordance with our invention;

Fig. 5, is a face view of a head and a portion of the Wire secured therein illustrating a modification of our invention, and

Figs. 6 and 7 are views in perspective illustrating a further modification within the scope of the invention.

WVith reference to the drawings, 1 indicates one form of wire head in common use, and 2 one end of a pile wire which the head is adapted to hold. A groove 3 is provided in one face of the head 1 for the reception of the end of the wire 2, it being common practice to secure the wire in the groove by means of solder.

It has been found, however, that this method of securing the wire in the head is more or less unsatisfactory owing to the comparative ease with which the wire breaks loose, and it is the object of this invention to provide more efficient means for securing the wire in the head.

In carrying out our invention, we employ a thin metal plate 4, which is adapted to be secured by welding or in other suitable manner over the groove 3 in the manner best shown in Fig. 4:, said plate having therein one or more perforations 5 which are disposed directly above the grooveand abovethe wire 2 when the end of the latter is inserted therein. The plate tthus, in effect, constitutes a wall of the recess in which the wire is'secu-red, and this wall is perforated forza purposenow to beidescribed.

Inassembling the parts, the plate-4 is first welded or otherwise secured-to the face-of the head 1. in the proper position. The end:

of the wire 2 is then inserted, and the apertures 5 filled in with solder or other suitable securing medium, this having the effect of forming a solder rivet or rivets which adhere to the outer face of the wire and extend upwardly to the outer face of the plate 3. If desired, the face of the wire 2 may be provided with indentations or recesses 6 so arranged as to respectively underlie the perforations 5 in the p-latel, and into which recesses the solder will flow.

A. securing means'such as described above has been found to possess characteristics of permanency far in advance of those previously commonly employed, this being attributed to thefact that the solder which constitutes the securing means is given a bearing against the sides of the apertures 5,

which sides lie substantially at right angles to the direction of any force tending to pull the wire from the recess. Such a bearing is not found in the original method of securing these elements together.

Considerable modification is possible within the scope of the invention, such for exl ample as that illustrated in Fig. 5, in which the apertures 5 in the plate 4 are of sufficient width to extend over the surface of the head 1 at either side of the groove 3, so that the solder rivets not only attach themselves to the wire but also to the head.

A still further modification is illustrated in Figs. 6 and 7, in which the head is shown consisting of two distinct portions 1 and 1 these portions being substantially half the thickness of the finished head, and the portions 1 and 1 having corresponding grooves 3 and 3 respectively which, when the portions are laid flat against one another, constitute the recess for the end of the wire 2. In this instance, one or both of the portions 1 are apertured over the grooves, and the parts are assembled by first thereafter inserting the Wire in'the. recess, and soldering through the apertures 5*, this having the effect of establishing in substance the same solder rivets as previously described. 7 a. Y

Still furthen'ino'difi'cation may be had With no departure from the essential features of the invention.

We claim:
